Abstract: A carrier particle (A) is previously treated with a compound (B) such as a silane coupling agent, if necessary. To the carrier particle, a free functional group is introduced by allowing a reactive group of the carrier particle (A) to react with a compound (C) such as a bisoxazoline compound. As a result, a reactive particle represented by the following formula (I):[C--(B1).sub.m ].sub.n --A--[(B2).sub.p --D].sub.q (I)wherein A is a carrier particle, C is an organic group having at least one free functional group, D is a hydrophilic or hydrophobic group, B1 is an organic group connecting the carrier particle A to the organic group C and B2 is an organic group connecting the carrier particle A to the hydrophilic or hydrophobic group; n is an integer of not less than 1, m and p are 0 or 1, q is 0 or an integer of not less than 1, m and p may be different according to n and q; and having a number of active sites can be obtained. A hydrophilic or hydrophobic group may be introduced to the carrier (A).

Abstract: A method for making a surface covering is disclosed which includes providing a surface covering having a backing layer, a foamable layer, and a design layer, wherein the design layer includes a portion of a pattern printed with at least one retarder composition. A wear layer is then provided on the design layer and the wear layer is cured. The foamable layer is thereby expanded to form a foam layer, and the pattern printed with at least one retarder composition is chemically embossed. The cured product is subsequently cooled to ambient temperature and then the top surface of the wear layer is subjected to a sufficient temperature to soften the wear layer. After being softened the wear layer is mechanically embossed with a surface texture, the embossed surface texture is set in the wear layer, and a top coat may then be provided on the embossed set wear layer. A surface covering having the various features described above is also disclosed.

Abstract: A method is disclosed of producing a blended fabric of polyester and cotton with superior low pilling characteristics. The method comprises polymerizing a melt consisting essentially of terephthalic acid, ethlyene glycol and at least about 1300 parts per million of pentaerythritol to an intrinsic viscosity of at least about 0.55 dl/g. The resulting polymer can be spun into filament, textured, cut into staple, spun into yarn, and formed into fabric. The method and resulting polyester also have advantages in the production of polyester bottle resin and the resulting bottles.

Abstract: The ability to transport body liquids in consumer products such as diapers, incontinents and feminine napkins is a key factor in their performance. This invention is designed to provide specific high fluxes (volume of liquid/(time*mass of polymer) of aqueous liquids in designated directions using bundles of new specially designed fibers. The key factors for the bundles are a high specific adhesion for the liquid of interest, a high specific volume of the bundle itself, and alignment of the fibers within the bundle. The invention includes novel liquid acquisition/distribution systems and absorbent products that include a liquid acquisition/distribution system which may incorporate the novel bundles of fibers.

Abstract: A new form of construction for synthetic cables used for the anchoring of floating platforms in offshore oil production is described. A desirable requisite for this application is that the durability of the cable is not affected by deterioration of its strong core by virtue of the aggressive mechanical action of particles of the sea bed which might penetrate the cable and reach its core. For this purpose a layer (2) to protect the core (1) comprising a strip of polymer material placed in helical fashion which permits the passage of water and prevents the passage of particles of the sea bed towards the core (1) is placed between the cable core (1) and its outer braided protective layer (2).

Abstract: This invention is a heat transfer ink ribbon that can exhibit a good heat transfer performance also on labels with a low chemical polarity, e.g., polyolefin type ones, and on matte labels with a rough surface, and yet can form high-quality images with a good stain resistance and solvent resistance even when the edge-face head type printer is used. This ink ribbon comprises a base material and formed on one side thereof an ink layer comprising a colorant and a binder containing a vinyl chloride resin and, and the vinyl chloride resin has at least one of an epoxy group and a strong-acid salt group in its backbone chain or side chain. An intermediate layer capable of undergoing cohesive failure at the time of heat transfer is preferably formed between the base material and the ink layer.
